Specification formingpart of Letters Patent No. 1131,27@ dated Septemberl0, 1872.

description thereof, reference being had to the accompanying drawingmaking part of this specification, in whichi Figure l, Plate l, is anelevation of one side of my improved machine. Fig. 2, Plate 1, is asection taken vertically and longitudinally through the center ofthemachine. Fig. 3, Plate 2, is a section taken transversely through themachine.

Similar letters of reference indicate corresponding parts in the severalgures.

This invention relates to improvements on the bolting-machine for whichLetters Patent were granted me on the 2lth day of Uctober, 1871,numbered 126,198.

The following description of my invention will enable othersl skilled inthe art to understand it.

In the accompanying drawing, A represents the body of the chest, uponwhich is a box, B, which is in communication with the chest by means ofan openin g, o, shown in Figs. 2 and 3. This opening tapers from itsends to the middle of its length, so that the draft up through it willbe as nearly uniform as possible throughout its` len gth.- The box Bcommunicates, through a trunk, G2, with a fan-case, G, which issustained outside of the chest A upon a bracket, D, and inside of whichis a fan, G1, applied on a shaft, @,carryin g a belt-drum, c. The chestA has long openings b through its sides for the inlet of air, which airis induced through said openings upward through the openin g o, andthrough the trunk and fan-case, as clearly indicated by Figs. 2 and 3.The fan receives its rotation from a beltwheel, g, on crank E, throughthe medium of a belt and the drum c. For the purpose of regulating theupward blast through the easeA and box B, a gate, a, is applied in thetrunk (l2, as shown by Figs. l and 3. This gate may be wholly `orpartially raised, as circumstances require. Between the box B and theair-inlet openings b is a screen, S, which is somewhat inclined, asshown in Fig. 2, and which is mounted upon the upper end of spring-mansc c, the lower ends of which arms are rigidly securedto horizontalsprings e', arranged below the inlets b, and secured at the middle oftheir length to the sides of the case A. The upper ends of thespring-arms e are rounded and iitted into corresponding recesses, whichare in bumpers n on the bottom of the screenframe, ,as shown in Fig. 2.The bumpers n are stepped or shouldered, and when the screen is vibratedthey strike the upper ends of xed blocks n and jar and shake the screen.Underneath of the spring-arm c are eccentric shafts ff, which extendtransversely across the Ichest A and have their bearings in the sidesthereof. The ends of the springs e rest upon said shafts, and are raisedor depressed by oscillating the shafts about their axes. On

one end of each shaft an index-hand, f2,is secured, which passes througha slotted sectorguide, f1, and is provided with a clamp-nut forconfining it at any desired point to its guide. It will be seen that 'bymoving the hand f2 the ends of the'screen can be raised or depressed; sothat when the screen is lowered the slides will come upon the block 'n nand produce the knocking-motion, the direction of the hands indicatingthe degree of inclination of the screen. P represents the hopper,through which the material to be treated is fed directly upon thehighest part of the screen S, and E represents a crankshaft carrying twobelt-drums, which receives rotation from a main shaft, i, through themedium of a belt. Motion is communicated to the screen S from thecrank-shaft E by means of a pitman, h, which is connected to the screenby an eyebolt and nut, l, as shown in Fig. 2. The main driving-shaft t'carries, besides its beltdrums, a pinion bevel-wheel, j', which engageswith a larger bevel-wheel, j, on one end of a prismatic shaft, J, shownin Fig. 2. This shaft J is located at the bottom of the chest A, betweentwo inclined planes, as shown in Fig. 3, and it is provided with bladesm applied obliquely around it, asshown in Fig. 2, for conveying theflour which falls through the screen to and disch arging it through thespouts p. Two of these spouts are provided with a sliding cut-oft', r,access to which Acan be had through an opening, T, shown in Fig. 3.

Operation. l

When motion is communicated to the screen, the conveyer, and fan, fromthe main shaft t', the middlin gs are fed into the machine through thehopperP, and fall directly upon the highest end of the screen. Thisscreen, which is driven by the crank-shaft E and pitman h, has a backand forward motion, which spreads the stuft and causes it to run downthe cloth. While it is thus passing over the cloth the fan Glexhauststhe air from the air-bbx B above and thus induces currents of airthrough the inlets b below the screen. These currents are drawn upwardthrough the cloth in a continuous stream, and operate to keep' all thelighter particles and specks at the top, land to allow such impuritiesas are not carried oft' through box B and fan-case G to pass oft' overthe screen-cloth, from which they fall through a vertical passage, S,and escape from the machine. The fine our which it is desired to savepasses through the screencloth and is discharged from the machine,through any one or more of the spouts p, through the bottom of thechest. The force of the currents of air through the screen can beincreased or diminished by adjusting the gate or valve a in the trunkG2. Y

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. The air-box B, .arranged on top of the chest A over the screen S, andcommunicating with the interior of this chest by means of an oblongpassage, o, in combination with a fanbox, C, which is arranged on oneside of the box A, and communicates with said air-box by means of atrunk, C2, which is provided with a regulatingvalve,va, substantially asset forth.

2. The vertical springs e, jointed at their upper ends to the screen S,and rigidly connected at their lower ends to horizontal springs e', incombination with adjusting devices for raising or depressing the screen,substantially as described.

3. The eccentric and adjustable shafts f, arranged beneath thescreensupporting arms e ef, substantially as described.

4. The socketed and shouldered bumpers n on the screen-frame, incombination with spring-arms e and fixed blocks a', substantially asdescribed.

5. The relative arrangement of the air-box B, the scrcen'S, the passageS', and the conveyer J m, as set forth.
